October 2017

NZGE is New Zealands national across flock and breed evaluation to identify the best rams for economic traits. The NZGE analysis includes all SIL performance-recording flocks, but flocks also have to satisfy specific criteria for NZGE Leader List reporting purposes. These include having good genetic connections with other flocks. Rams from other flocks are listed if they have been used in connected flocks with sufficient progeny evaluated.

The following files can be downloaded as SIL formatted reports (pdf) or as comma delimited text files (csv) by clicking on the links below.

The October 2017 Leader Lists include a new Trait Leader List for Body Condition Score, with 57 flocks currently connected for Body Condition Score.

From September 2017 the NZGE Leader Lists include the two NZGE developments released in late August, updated relative economic values (REVs) and the incorporation of DNA information into the merit prediction. To reflect the inclusion of DNA information when available, breeding values are now reported as gBVs.

For individuals with performance data only the gBV will equal the eBV.
For individuals with molecular information, the eBV and mBVs (molecular BV) are combined on the basis of the relative accuracy of each BV to produce gBV.

Further details on the update Breeding Objectives (REVs), Capped reproduction and Breeding Values from NZGE (gBVs) can be found on the SIL website under News or in Technical Notes.
